' PROJECTILE.

SPECIFICATION forming part of Letters Patent No. 620,387, dated February28, 1899. Application filed June 25,1898. Serial No. 684,525. (Nomodel.)

, To all whom) zit may concern:

' Norway, have invented certain new and useful Improvements in andRelating to Projectiles;- and I do hereby declare that the following isa full, clear, and exact description of the same, such as will enableothers skilled in the art to make and use my invention.

This invention has relation to explosive projectiles, and moreparticularly to shrapnel.

It is well known that the time and combination fuses of explosiveprojectiles, more particularly the shrapnel-fuses, when exposed todampness, as is frequently the casein magazines both on land and aboardships, are seriously afiected in so far as their efficiency andreliability are concerned, or, as is frequently the case, their functionis entirely destroyed. It is the experience of all those connected withthe handling and use of these projectiles that whenever they have .beenexposed to dampness the fuses, if not rendered entirely useless, areseriously affected, in so far as the time of combustion is concerned,according as more or,less moisture has penetrated into the fuse-tubes.

The object of this'invention is to provide means whereby these fuses canbe thoroughly protected against atmospheric influences in a simple,cheap, and reliable manner and so that the protective agent may in amoment be removed for the purpose of adjusting the fuse to a giventimeor for any other purpose.

In the accompanying drawings, Figure 1 is a fragmentary elevation of aprojectile with the protective cap applied thereto and shown in section.Fig. 2 is a like view showing the cap cemented to the projectile andprovided with a waterproof coating.

In carrying out my invention I apply a protective cap 0, of rubber, overthe fuse F im-' mediately after its insertion into the projectile- P insuch manner that such cap can be readily removed when the projectile isdelivered from the magazine. To this cap 0, I

give such form as to correspond with the point of the projectile, so asto adapt it to be drawn over such point and over the fuse in such manneras to completely exclude all access of air to said fuse, in that saidprotective cap is caused to completely cover the fuse and the adjacentparts of the projectile.

into a solution of asphalt, preferably a solution of asphalt in tar, asshown at a, Fig. 2, whereby any pores in the rubber protective cap areefiectually closed. It is obvious that this cap can be readily andalmost instantaneously removed when the projectile is to be used.

Experiments have shown that the fuse of projectiles protected asdescribed remained unaltered after exposure of the projectileto dampnessfor a long time, during which un protected fuses were either veryseriously inj ured or rendered completely useless.

Having thus described my invention, what I claim is- 1. An explosiveprojectile, its fuse, and a rubber cap applied over the fuse and a portion of the projectile and cemented thereto, for the purpose set forth.

2. An explosive projectile, its fuse, a rubber cap applied over the fuseand a portion of the projectile and'cemented thereto, said cap coatedwith asphalt, for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
